About These Birds
Crested Partridge
A small partridge (~250 g) of family Phasianidae, males with vivid crimson crest and iridescent green plumage. Found in lowland tropical rainforests of Southeast Asia including Thailand, Malaysia, Sumatra, and Borneo. Forages on the forest floor for fallen seeds, fruits, and invertebrates. Vulnerable; dependent on primary lowland forest, heavily impacted by deforestation and palm oil expansion.
Lesser Prairie-chicken
A medium-sized grouse (~725 g) of family Phasianidae, paler than Greater Prairie-chicken with crimson-orange air sacs in males. Inhabits arid mixed-grass and shinnery oak prairies in the southern Great Plains of the United States. Feeds on plant matter and invertebrates. Vulnerable; severe population declines due to oil and gas development, overgrazing, drought, and loss of native shrub prairie.
